The answer is 3,33 moles.
The formula shows that there is one atoms of iron in each formula unit of FeCl3, and by definition the number of molecules or formula units in a mole is Avogadro's Number. Therefore, 5.33 moles contains 5.33 X Avogadro's Number of atoms, which is 3.21 X 1024 atoms, to the justified number of significant digits.
1 mol of Na contains 6.02 x 1023 atoms (avogadro constant). Amount of Na = (1.31x1024) / (6.02x1023) = 0.227mol
Convert 1.35 × 1024 atoms of carbon to moles of carbon
The answer is 0,199 moles.
The chemical formula for water is H2O; therefore each formula unit has three atoms. Avogadro's number is defined as the number of formula units per mole. Therefore, the answer to the stated question is 3 X 6.022 X 1023 = about 1.8066 X 1024 atoms. (If the value "3" is not considered exact, only one significant digit is justified; in that instance, the answer should be written. as 2 X 1024.
1 mole CaCl2 = 6.022 x 1023 formula units CaCl2 1.26 x 1024 formula units CaCl2 x 1mol CaCl2/6.022 x 1023 formula units CaCl2 = 2.09 moles CaCl2
A mole is 6.022 × 1023 so 2.41 × 1024 molecules CaCl2 ÷ 6.022 × 1023 = 4.00 moles CaCl2.
4.5 moles NaCl = 4.5000000000001 formula units NaCl *******************2nd Opinion************* 4.5 moles of NaCl would contain 4.5 x (6.02 x 1023) formula units. = 2.7 x 1024 formula units
9.54*1024
Sodium chloride is an ionic crystalline salt, and does not form molecules. One unit of sodium chloride is called a functional unit. It is the lowest whole number ratio of ions represented in an ionic compound. 1 mole = 6.022 x 1023 formula units of NaCl 3 moles NaCl x 6.022 x 1023 formula units/mole = 1.8 x 1024 formula units of NaCl
The formula shows that there is one atoms of iron in each formula unit of FeCl3, and by definition the number of molecules or formula units in a mole is Avogadro's Number. Therefore, 5.33 moles contains 5.33 X Avogadro's Number of atoms, which is 3.21 X 1024 atoms, to the justified number of significant digits.
1 mol of Na contains 6.02 x 1023 atoms (avogadro constant). Amount of Na = (1.31x1024) / (6.02x1023) = 0.227mol
Vanadium does not have moles but rather formula units. The formula unit for vanadium is a single atom. Therefore, the number of formula units in any number of atoms is equal to the number of atoms divided by Avogadro's Number, in this instance 7.17 X 10-3 formula units.
Convert 1.35 × 1024 atoms of carbon to moles of carbon
4,96 x 1024 molecules of glucose is equal to 8,236 moles.
The answer is 0,199 moles.
The equivalent is two moles.
